VEHICLE-TIRE.

lthe following is a full, clear, and exact descri tion.

y invention relates to vehicle tires, my more particular purpose beingto provide a tire construction affording a maximum of elasticity andstrength, coupled with simplicity and cheapness and offering a number ofspecial advantages, as hereinafter described.

Reference is to be had to the accompanying drawings forming a part ofthis speciication, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a fragmentary side elevation showing a wheel equipped withmy improved tire; Fig. 2 is an enlarged fragmentary section through aportion of the wheel rim and tire, this view showing the separateresilient cushions, means for holding the same in position, the cups forengaging the resilient cushions, and the mechanism conunected with thecups and including springs serving to increase the resilience of thetire; Fig. 3 is a fragmentary cross section on the line 3-3 of Fig. 2,looking in the direction of the arrow, through the wheel rim and tire,this view showing the springs, and further showing the make-up of thetread of the tire; Fig. 4 is a view somewhat similar to Fig. 3, buttaken on the line 4-4 of Fig. 2, looking in the direction of the arrow,and showing particularly the construction of the resilient cushions;Fig. 5 is a longitudinal. section upon the line 5-5 of Fig. 2, lookingin the direction of the arrow, and showing thecups and their mountingsfor holdinr the resilient cushions; Fig. 6 is a detai. showing inenlarged section one of the guide pins and the spring encircling it forthe purpose of increasing the resilience of the tire; Fig. 7 is afragmentary perspective of a portion of the tire, showin how the outercovering is applied and he d in position; and Fig. 8 is a fragmentaryperspective of one of the overlapping plates whichl support the cups andpress the latter against the resilient cushions.

At 9 is a hub and radiating from it are spokes 10 supporting a woodenrim 11. A

metal rim 12 is mounted upon this wooden rim and is provided with lugs13 of annular form spaced equidistant and integral with the metallic rim12, and also`with cupped edges 13, as shown in Figs. 1, 4 and 7. Anumber of guide pins 14 are screwed into the lugs 13 and thus securedrigidl in position. Each guide pin 14 is encircle by a spiral sprin 15and is provided with a head 1G. Encircling each guide pin 14 isy a ring17 havin its lower edge conveXed, as indicated in 1ig. 6. Each ring 17engages a bearing 18, the upper surface of which is coneaved in order tofit the rin, 17. Each bearing 18 is disposed intermec iate a pair ofsleeves 20, 21, separated by a slot 19, as will bo understood from Figs.2 and 5.

The sleeves 20 and 21 encircle pins 22, which are integral with thebearings 18 and extend in opposite directions therefrom. A number of cu)s 23 provided with end walls 24, 25, parallel with each other, and also10- vided with side walls 23u slightly curve as indicated in Fig. 5, aredisposed within the tire. The pins 22 are tension members, andconsiderable strain is at times thrown upon them. The pins are providedwith threaded ends 28, 28 which extend through holes in the end walls 24and 25, and are secured by nuts 26, 27. The pins 22 and cups 23 togetherform a continuous vannular member. Guard plates 29 (see Fig. 3) aremounted upon the threaded ends 28 and project downwardly therefrom, aswill be understood from Figs. 2 and At 30 are shown cushions ofresilient material, preferably rubber and made hollow. These cushionsare secured in position by aid of lugs 31 extending outwardly from themetallic rim 12. Two layers 32, 33 of fabric, preferably canvas, aremade integral with each other and encircle two rings 34 of rubber orother resilient material, as will be understood from Figs. 3 and 4. Aplate 35 of rubber or other resilient material is made thick at itsmiddle portion and tapers, off at its edges 36 to nothing. This plateparl as these cushions rest in cups 23 the pressure the leather plate 37which, for the purpose, is provided with slots 42 whereby its innerportion is separated into tongues 40, each tongue carrying two hooks39a, as will be understood vfrom Fig. 7, the tongues terminating inapertures 41. The rubber plate and the leather plates 37, 38 are allcemented together at all points below the holes 41, so as to render theouter parts of the tire as nearly solid as practicable. The inner and.

outer layers 32, 33 of fabric are also provided with slots 44terminating in holes 43. The sleeves 2O and tongues 2Oa upon whichtheyare supported (see Fig. 8) are integral with a body portion 20",having a semi-cy i drical part 20, all of these parts being ntegral andtogether forming a plate, a number of these plates overlapping eachother, as will be understood from Fig. 2.

My inventiony is used as follows: The parts being assembled, wheneverthe weight of the vehicle rests upon thel tire the studs 39 engage theground and the weight'is distributed to a great extent throughoutvarious portions of the wheel.` The pressure of the wooden rim 11 andmetallic rim 12 downward forces the cushions 30 downward, and

is, of course, applied to these cups. Pressure is also transmitted tosome extent from the metallic rim. 12 through the spiral springs 15 tothebearings 18, and thence to v f 954,361 f the tongues 20a. In case ofan excessive load upon the vehicle, the guard plates 29 may sometimesengage the inner surface'of the overlapping plates 12b, but in thisevent not much pressure is likely to rest upon these overlapping plates,and whatever weight does rest there is distributed `as nearly equally aspracticable. The overlapping of the plates 20b allows them a slightmovement relatively to each other with the result that undue rigidity inthe` tire is avoided.

Having thus described my invention, lI claim `as new and desire tosecure by Letters Patent:

In a device of the character described, the combination of a rim,cushions mounted thereupon, a composite member, having generally anannular form, encircling said rim and provided with portions engagingsaid cushions, a plurality of members arranged in a general annular formand connected to said composite member, said last-mentionedl membersoverlapping one another, and a tread supported upon said last-mentionedmembers. Y

In testimony whereof I 'have signed 'my naine to this specification inthe presence oft two subscribing witnesses.
